WRT
The Workload Response Time (WRT) sampler produces a warning when the response time for workloads that match your specified selection criteria reaches or exceeds the threshold you specified.
This Exception Monitor sampler can be used only from the MainView for z/OS product.
Syntax
The parameters are defined as follows:
Parameter | Description |
|---|---|
int | is the length of the report period in intervals; the default is 30 seconds (one interval) |
name | is the name of the workload to be monitored |
name* | indicates a partial workload name You can specify partial names by using a wildcard character (an asterisk), which indicates that only the characters prior to the asterisk are to be used for comparison. |
period | represents the performance period for the workload, which is to be used when checking the response time against the threshold value |
seconds | is the response-time threshold expressed in hundredths of a second |
Example
Assuming a report interval of 30 seconds, this example illustrates the use of four separate sampler definitions:
WRT 2,TSO*,1,70
WRT 2,TSO*,2,200
WRT 2,TSO*,3,300
WRT 2,TSO*,4,400
Each definition defines a response-time threshold for a specific performance period. A partial name of tso* is specified for each, indicating that any workload name that begins with tso is to be considered.
- The first definition indicates that a warning message should be issued if the response time for performance period 1 is 0.7 seconds or greater.
- The threshold for performance group 2 is two seconds.
- The threshold for performance group 3 is three seconds.
- The threshold for performance group 4 is four seconds.
Warning message
The following warning message is issued by the WRT sampler:
PWSWRT00 *WARNING* Workload wwwwwwww response time is xxx.xx seconds
Message PWSWRT00 indicates that the overall response time for workload wwwwwwww is xxx.xx seconds.
